Consequently, the accumulation of dust over the surface of PV cells is considered as one of the main causes for lowering the electrical or conversion efficiency (η El) of PV cells. The loss in the effectiveness of the PV module depends on the mass of dust accumulated and particle size over it as it covers the solar module.
In this study, an investigation about recent works regarding the effect of environmental and operational factors on the performance of solar PV cell is presented. It is found that dust allocation and soiling effect are crucial, along with the humidity and temperature that largely affect the performance of PV module.
Solar radiation (sunlight) falling on the photovoltaic (PV) module is converted into electricity by the PV effect. The power production of the PV module depends on ambient conditions.
Once water comes into the PV module, the accumulated moisture within the module in the presence of other climatic stressors can lead to all forms of degradation modes in PV module’s components and other packaging materials (Ballif et al., 2014, Kudriavtsev et al., 2019, Wohlgemuth and Kempe, 2013).
The characteristics of the accumulated dust (type, size, shape, meteorology, etc.) are determined by its geographical source, and its effect is not only to reduce the solar radiation reaching the surface of the PV, but also to adhere to these surfaces and scratched and work on corrosion and reduce their life span.
Moisture ingress in photovoltaic (PV) modules is the core of most degradation mechanisms that lead to PV module power degradation. Moisture in EVA encapsulant can lead to metal grids corrosion, delamination and discolouration of encapsulants, potential induced degradation, optical and adhesion losses.
